A CIO stays focused
A CIO doesn't have to follow any of these, because these aren't hard and fast rules. I have seen some extremely successful CIOs staying completely free from such things and still coming out on top, voted by his employees as the best boss. The reason is you only have to have one thing, unbreakable focus and that focus would drive you to become a leader. A successful CIO may stay aloof of the employees woes, but he'll never turn a deaf ear to it, he will solve their problems even without interacting much. My favorite boss was a mysterious man whose personal life he never used to discuss, but in all our lives solutions we used to find his hand. He was an amazing person.
